  • Beyond Relational Databases
    EXPERT ANALYSIS BY MARCOS ALBE, SUPPORT ENGINEER, PERCONA Beyond Relational Databases: A Focus on Redis, MongoDB, and ClickHouse Many of us use and love relational databases… until we try and use them for purposes which aren’t their strong point. Queues, caches, catalogs, unstructured data, counters, and many other use cases, can be solved with relational databases, but are better served by alternative options. In this expert analysis, we examine the goals, pros and cons, and the good and bad use cases of the most popular alternatives on the market, and look into some modern open source implementations. Beyond Relational Databases Developers frequently choose the backend store for the applications they produce.

  • Mariadb Presentation
    THE VALUE OF OPEN SOURCE MICHAEL ”MONTY” WIDENIUS Entrepreneur, MariaDB Hacker, MariaDB CTO MariaDB Corporation AB 2019-09-25 Seoul 11 Reasons Open Source is Better than Closed Source ● Using open standards (no lock in into proprietary standards) ● Resource friendly; OSS software tend to work on old hardware ● Lower cost; Usually 1/10 of closed source software ● No cost for testing the full software ● Better documentation and more troubleshooting resources ● Better support, in many cases directly from the developers ● Better security, auditability (no trap doors and more eye balls) ● Better quality; Developed together with users ● Better customizability; You can also participate in development ● No vendor lock in; More than one vendor can give support ● When using open source, you take charge of your own future Note that using open source does not mean that you have to become a software producer! OPEN SOURCE, THE GOOD AND THE BAD ● Open source is a better way to develop software ● More developers ● More spread ● Better code (in many cases) ● Works good for projects that can freely used by a lot of companies in their production or products. ● It's very hard to create a profitable company developing an open source project. ● Not enough money to pay developers. ● Hard to get money and investors for most projects (except for infrastructure projects like libraries or daemon services). OPEN SOURCE IS NATURAL OR WHY OPEN SOURCE WORKS ● You use open source because it's less expensive (and re-usable) ● You solve your own problems and get free help and development efforts from others while doing it.

  • Mysql Cluster – Evaluation and Tests, OCTOBER 2, 2012 1 Mysql Cluster – Evaluation and Tests
    MySQL Cluster – Evaluation and Tests, OCTOBER 2, 2012 1 MySQL Cluster – Evaluation and Tests Michael Raith (B.Sc.), Master-Student F Abstract Websites or web applications, whether they represent shopping systems, on demand services or a social networks, have something in common: data must be stored somewhere and somehow. This job can be achieved by various solutions with very different performance characteristics, e.g. based on simple data files, databases or high performance RAM storage solutions. For today’s popular web applications it is important to handle database operations in a minimum amount of time, because they are struggling with a vast increase in visitors and user generated data. Therefore, a major requirement for modern database application is to handle huge data (also called “big data”) in a short amount of time and to provide high availability for that data. A very popular database application in the open source community is MySQL, which was originally developed by a swedisch company called MySQL AB and is now maintenanced by Oracle. MySQL is shipped in a bundle with the Apache web server and therefore has a large distribution. This database is easily installed, maintained and administrated. By default MySQL is shipped with the MyISAM storage engine, which has good performance on read requests, but a poor one on massive parallel write requests. With appropriate tuning of various database settings, special architecture setups (replication, partitioning, etc.) or other storage engines, MySQL can be turned into a fast database application. For example Wikipedia uses MySQL for their backend data storage. In the lecture “Ultra Large Scale Systems” and “System Engineering” teached by Walter Kriha at Media University Stuttgart, the question “Can a MySQL database application handle more then 3000 database requests per second?” came up some time.

  • Innodb 1.1 for Mysql 5.5 User's Guide Innodb 1.1 for Mysql 5.5 User's Guide
    InnoDB 1.1 for MySQL 5.5 User's Guide InnoDB 1.1 for MySQL 5.5 User's Guide Abstract This is the User's Guide for the InnoDB storage engine 1.1 for MySQL 5.5. Beginning with MySQL version 5.1, it is possible to swap out one version of the InnoDB storage engine and use another (the “plugin”). This manual documents the latest InnoDB plugin, version 1.1, which works with MySQL 5.5 and features cutting-edge improvements in performance and scalability. This User's Guide documents the procedures and features that are specific to the InnoDB storage engine 1.1 for MySQL 5.5. It supplements the general InnoDB information in the MySQL Reference Manual. Because InnoDB 1.1 is integrated with MySQL 5.5, it is generally available (GA) and production-ready. WARNING: Because the InnoDB storage engine 1.0 and above introduces a new file format, restrictions apply to the use of a database created with the InnoDB storage engine 1.0 and above, with earlier versions of InnoDB, when using mysqldump or MySQL replication and if you use the older InnoDB Hot Backup product rather than the newer MySQL Enterprise Backup product.

  • A Closer Look at Mysql Cluster an Architectural Overview - Mariadb White Paper - 08-26-13-001.Docx Page 1
    w: www.mariadb.com e: [email protected] MySQL Cluster Internal Architecture Max Mether MariaDB Keywords: MySQL Cluster, MySQL, High Availability, HA, Clustering, Architecture 1 Introduction MySQL Cluster is tightly linked to the MySQL server, yet it is a separate product. Due to its distributed nature, MySQL Cluster has a far more complicated architecture than a standard MySQL database. This presentation and white paper will describe the internal architecture of the MySQL Cluster product and the different mechanisms and process that exists to insure the availability of the cluster. We will also take a close look at the data and message flow that takes place between the nodes in the cluster during different types of operations. 2 MySQL Cluster Features MySQL Cluster can be distinguished from many other clustering products in that it offers five nines availability with a shared-nothing architecture. Most clustering products use a shared-disk architecture. Using a shared- nothing architecture allows the cluster to run on commodity hardware, thus greatly reducing costs compared to shared-disk architecture. Having a shared-nothing architecture does, however, come with a different cost, namely, a more complex way of ensuring high availability and synchronization of the nodes which is mainly seen as increased network traffic. MySQL Cluster also provides ACID transactions with row level locking using the READ-COMMITTED isolation level. MySQL Cluster is, in general, an in-memory database, however non-indexed data can be stored on disk and the disks are also used for checkpointing to ensure durability through system shutdown. MySQL cluster provides unique hash indexes as well as ordered T-tree indexes.
